Replacing Supervisor Modules

To avoid packet loss when removing a supervisor module from a Cisco MDS 9500 Series Director, take
the supervisor modules out of service before removing the supervisor module.
Use the out-of-service command in EXEC mode before removing the supervisor module.
Where slot indicates the chassis slot number in which the supervisor module resides.
Note You must remove and reinsert or replace the supervisor module to bring it into service.

Migrating from Supervisor-1 Modules to Supervisor-2 Modules

Supervisor-1 modules and Supervisor-2 modules cannot be used in the same switch, except for migration
purposes. Both the active and standby supervisor modules must be of the same type, either Supervisor-1
or Supervisor-2 modules. For Cisco MDS 9513 Directors, both supervisor modules must be Supervisor-2
modules.
The procedure described in this section ensures that your configuration is correctly synchronized after
completing the migration.
Migrating your supervisor modules is a disruptive operation.
Caution
Migrating from Supervisor-2 modules to Supervisor-1 modules is not supported.
